Book 18
And now he would even have dragged it off and have won imperishable glory, had not Iris fleet as the wind, winged her way as messenger from Olympus to the son of Peleus and bidden him arm. She came secretly without the knowledge of Zeus and of the other gods, for Hera sent her, and when she had got close to him she said, "Up, son of Peleus, mightiest of all humankind; rescue Patroklos about whom this fearful fight is now raging by the ships. Men are killing one another, the Danaans in defense of the dead body, while the Trojans are trying to hale it away, and take it to windy Ilion: Hektor is the most furious of them all; he is for cutting the head from the body and fixing it on the stakes of the wall. Up, then, and bide here no longer; shrink from the thought that Patroklos may become meat for the dogs of Troy. Shame on you, should his body suffer any kind of outrage."

And Achilles said, "Iris, which of the gods was it that sent you to me?"
Iris answered, "It was Hera the royal spouse of Zeus, but the son of Kronos does not know of my coming, nor yet does any other of the immortals who dwell on the snowy summits of Olympus."

Then fleet Achilles answered her saying, "How can I go up into the battle? They have my armor. My mother forbade me to arm till I should see her come, for she promised to bring me goodly armor from Hephaistos; I know no man whose arms I can put on, save only the shield of Ajax son of Telamon, and he surely must be fighting in the front rank and wielding his spear about the body of dead Patroklos."
Iris said, ‘We know that your armor has been taken, but go as you are; go to the deep trench and show yourself before the Trojans, that they may fear you and cease fighting. Thus will the fainting sons of the Achaeans gain some brief breathing-time, which in battle may hardly be."
Iris left him when she had so spoken. But Achilles dear to Zeus arose, and Athena flung her tasseled aegis round his strong shoulders; she crowned his head with a halo of golden cloud from which she kindled a glow of gleaming fire. As the smoke that goes up into heaven from some city that is being beleaguered on an island far out at sea - all day long do men sally from the city and fight their hardest, and at the going down of the sun the line of beacon-fires blazes forth, flaring high for those that dwell near them to behold, if so be that they may come with their ships and succor them - even so did the light flare from the head of Achilles, as he stood by the trench, going beyond the wall - but he aid not join the Achaeans for he heeded the charge which his mother laid upon him.
